Based on an August 2020 extract of the California Plant Rescue Database, California Botanic Garden has collected 1 seed accessions of Acanthoscyphus parishii var. goodmaniana from 1 plant occurrences listed in the California Natural Diversity Database. These collections together emcompass 60 maternal plants

Restricted to a carbonate belt in the northeastern San Bernardino Mountains, San Bernardino County, California. Approximately 14 occurrences are believed extant (with another 1 historical and 1 of unknown status) within an area of approximately 165 square kilometers. Population size was estimated to be 20,000-35,000 plants, although it fluctuates greatly from year to year, so is likely significantly less in some years. Habitat destruction and degradation associated with limestone mining is the major threat to this taxon. Lesser threats include off-highway vehicle use, recreational and urban development, potential power line and hydroelectric development projects, and extirpation from random events since plant numbers fluctuate widely. The U.S. Fish and Wildlife Service (2002) has designated Critical Habitat and the U.S. Forest Service has developed the Carbonate Habitat Management Strategy (2003) with the aim of mitigating these threats.

The primary threat to O. parishii var. goodmaniana is limestone mining in the region. Open terraced mining, overburden dumping, and road construction all result in destruction of habitat for these carbonate endemic plant species. Off highway vehicle use

The estimated number of plants in 1990 was fewer than 3,000, in the four known populations at the time. There are currently 16 occurrences listed in the California Natural Diversity Database (CNDDB 2007), however 50 occurrences were documented in 1998 (Soza 1998). Because O. parishii var. goodmaniana is an annual species, the number of individuals fluctuates from year to year depending on the winter and spring rainfall and temperatures favorable for germination and seedling establishment (USFWS 1997).

There has been limited investigation on the biology and ecology of O. parishii var. goodmaniana. Ongoing revegetation trials on former limestone quarry sites provide some insight into community ecology on carbonate substrates, and surveys conducted on the San Bernardino National Forest have expanded knowledge of these species distribution patterns (USFWS 1997, Soza 1998).

The primary conservation strategy for O. parishii var. goodmaniana is to implement the Carbonate Habitat Management Strategy and to improve knowledge of its distribution. Critical habitat for O. parishii var. goodmaniana was designated by the USFWS in 2002 (USDA FS 2007).

Management needs that have been identified by the USFWS include protection of significant extant populations by developing a reserve system on federally owned land of occupied areas, buffer zones, and habitat connections; restoring habitat, reintroduction efforts and enhancing populations; monitoring populations; and conducting surveys and taxonomic assessments to locate new populations and resolve questions about the identity of several existing populations (USFWS 1997).
